First off, I'm new to the forum and the search button gave me a php Fatal Error, not enough memory allocated (in other news, it's usually good to catch those exceptions for security reasons). In any event, I apologize if this question has been asked and answered but since I couldn't find it..

What's the the best cold weather (like Chicago-cold) car cover for a 2010 BMW 128i? (Preferably $250 or less) Where do you generally go for such things?

Thanks a lot! I'm going to do some satellite radio hacking soon and I plan to post relevant results from that.
